Thisfinvention relates to an improvement in Vadjustable slicing lmives adaptedfor the slicing of meat or other articles of food.

The slicing of meat or thelike requires great skill in gauging the desired thickness Aof the slice so as to obtain uniform slices of. thedesired thickness, and-this is not possiblel by untrained persons Whoare often called Vupon to produce such slices. Even with the vutmost skill, the slices are not always uniform, especially when' it may be desired tovary the thicknessunder different conditions.V f

The object of this invention is'to'provide for .the productionA of a Vuniforrn thickness of slice which is adjustable to different Vvdegrees under the control of the operator,l which is accomplished by the provision of an" adjustable guard associated with the slicing blade and extending lengthwise thereof to regulate thethickness of the slice and toV insure that the slicev may be formed uniformly. Y l Y Y Another object of the invention is to improve the construction of the slicing knife by the provision of a double edged blade which is mounted under tension, so as to insure of positive -accu rate slicing thereby; by providing suchrperforations in the guard that the edges of1the'blade being manipulated therebelow will be readily visibleto the` operator; `and byV constructinglthe guard, so `as to expose an "edge of theb-lad'e beyond the guard, -at least at one end thereof, whereby ,the guard will notinterfere vwith the slicing action of the bladewhencutting against a solid object, such as a bone in apiece of'n'ieat.A

These features are provided indierent em- 1 bodirnents of the invention .which "are illustrated in thc accompanying drawing, in which: n .Figyl is a side elevation of one, formiofthe adjustable slicing knife; y Fig. 2 is a bottom plan view thereof; i L

VThe opposite. ends ofthe blade i 5 are provided withper'forationstherein, oneof which engages'fa-pin B, projectingjfrom the end of vthearinZ, which pin is shown as having a slightly lateral bend tohold'thebladein place thereon, soasto anchorfsaid end of thexblade. The oppositev end of the blade'l is engagedlbyl a J-bolt l, the r'shank'offvvliic'h extends through the arm 3 and receives 4a nut y8', threaded thereonvforv adjusting'said-bolt to vary the tension-of the blade, which nut maybe removed 'also for re'- movalof.thebladewhen desired for cleaning,

frame. The arm 3 is shown as having a handle loosened sufficiently vto VdisconnectA the adjacent endof the blade 5 therefrormthat'the.blade may bedetachedreadily .from the pin for sharpening, cleaning,1or the substitution .of a ne'wLblade, Yas may be desired. f f i k Associated with the blade 15 and v extending t l lengthwise V)thereof inV parallel spacedfrelation therewith, isa guard whichisgshown in Fig. 2, as ofsomewhat greater width, than the `blade 5 ,toext'end outwardly beyond the edges thereofv on both sides. The guard 9 is supported by bolts VI I adjacentopposite ends thereof, whichbolts' have grooved heads il, received 'in transverse-slots I2 vformed Vin the opposite endhportions of 'thejguard S for freedomv of transverse sliding movement of the guard 9 relative to V.the bolts l Il; Such sliding movementis. opposed by aleaf sprlnglS formed Y n of spring wire, the opposite ends of Whichextend through the heads l l of the bolts, andthe interchored atll bysolderng, Welding, ortho lil;e, "to the back 0fthe guard 9, whereby if. transverse blade 5 by'adjustablewwinged nuts .I5 threaded on thebolts I and may beheld in an adjusted` Y' `position by lock nuts I6 threadedthereon, which nuts l5 and I6 cooperate with the back l to ysupport the guard therefrom. lThe extent of-ad' justment of opposite endportions ofthe guard 9 The may be indicated by graduations l1 provided on K being sliced.

The manner of use of the knife will be evi-H the arms 2 and 3 to insure that both end portions may be adjusted to the same extent and that the guard will be disposed parallel with the blade 5 for obtaining slices of uniform thickness. Since the slicing operation is usually accomplished in a horizontal direction with the blade on the underside of the back l, the guard 9 is provide-d with a multiplicity of perforations I8 therein, as shown in Figs. 2 and 4to provide for fullvisibility of the edges of the blade by the operator for certainty of slicing operation,` so that hem-ay -see` the portion of the meat or other product that `is dent to accomplish the desired slicing operation, but the operator may adjust the thickness of the slice by Varying the position of the guard Si relative to the blade 5. This is done by rst loosening the lock nuts i6 and then turning the nutsV l5 to moveA the guard 9 toward or from the blade 5, asv maybe desired, the same adjustment-being made at each end of the guard, as indicated by the graduations l1. Y

After thus adjusting the guard 9, the locknuts IS areretightened, and the slicing operation may proceed inthe usual way. Where a piece-of meat is kbeing sliced as it rests on a supportl or holder, the slicing operation is `usually in ,a rhorizontal direction, when theperfo-rations I8 afford full visibility'at'the point of slicing, so that the operator may see what is being cut. Theg'guard 9 is placed against the face of therpie'ceci meat orl ,other object overlapping the face while the blade engages theedge thereof, thereby regulating the thickness of the slice to becut.

, `While the guard v9` preferably extends outward beyond the Ylateral edges of the blade to regulate the thickness of the slice,1this would normally interfere with the `slicingoperation Vat or adjacent a bone vcr other solid object, but tlremcuntverse sliding movement relative thereto. To` provide for the access of the blade 22 to the bone Y or other solid object to accomplish the slicing blade 22, leaving the opposite edges of the blade exposed while the major portion of the guard V23 overlaps the edges ofthe blade to form a guard therefor and to regulate the thickness of the slice inthe manner desired above. This form is used in the same way as the form shown in Figs. 1 to 4 and `may be adjusted to vary theV thickness'of the slice as described.
